hello ive been dealing w/Telsco for 13mnths- its an estate home. Ive had NO issues w/re-programing keypad- from either the techs or the opr mgr.- Patti Jones. Their support was topknotch! Ive even had false trips calls & wasn't charged or chastised for the calls. They know customer service!. Well done telsco! Thank you Patti for everything! Rhonda.R
